Scientists simulate tiny bacteria-powered 'windfarm'

A team of scientists from Oxford University has shown how the natural movement of bacteria could be harnessed to assemble and power microscopic 'windfarms' - or other man-made micromachines such as smartphone components.

Molecular motors: Pirouetting in the spotlight

German scientists have developed a new class of molecular motors that rotate unidirectionally at speeds of up to 1 kHz when exposed to sunlight at room temperature. This unique combination of features opens up novel applications ...

A folding drone that's ready for takeoff in a snap

Thanks to the power of its rotors, this fold-up quadrotor extends its articulated arms and takes off in a fraction of a second. This prototype will be viewed by specialists on May 25 at the International Conference on Robotics ...

Generating eco-friendly power with metal rotor blades

Wind turbines deliver environmentally friendly electricity. Yet the fiber-reinforced plastics often used in very large rotor blades are almost impossible to recycle. Not so with steel blades: since these are composed of steel, ...
